Sealing ring, for sealing between WT-Eckes and filter head. The use of other sealing rings (e.g. O-rings with circular cross section, too small/to large hardness) often leads to problems, which express themselves in air inlet at the sealing surface filter headf/wt-eckes. Therefore we absolutely recommend the WT-Eckes-DR from our program.
